In case anyone's interested, here's a short vid I took using the Rokinon 8mm in Nikon mount and EOS chipped adapter on a T2i.
The camera was set on the front dash of the old minivan using a beanbag of sorts consisting of several rags stuffed into one of my clean athletic sox. The lens was set a f8 (I think) and the focus at 10 ft which effectively made the lens Point & Shoot. The camera now has the Magic Lantern package installed in it which greatly expands its capabilities. I make no excuses for the composition as this was just a test of this lens and camera combination.
